The Relationship between Negative Trauma-Related Cognitions and Psychosocial Functioning in Veterans with Posttraumatic Stress Disorder and Alcohol Use Disorder

Abstract

Background

The comorbidity of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) is highly prevalent and associated with especially poor psychosocial functioning. Negative trauma-related cognitions are theoretically proposed to be associated with poor psychosocial functioning in PTSD, but few studies have examined the association between negative trauma-related cognitions and psychosocial functioning in PTSD/AUD. Evaluating this association may provide evidence of a potential treatment target for improving psychosocial functioning in PTSD/AUD. We hypothesized that negative trauma-related cognitions, including cognitions about the self, world, and self-blame, would be independently associated with poor psychosocial functioning in the following domains: vitality, psychosocial well-being, role limitations due to emotional distress, and social functioning.

Methods

We examined the relationship between negative trauma-related cognitions and psychosocial functioning in 145 treatment-seeking veterans with PTSD/AUD using multiple linear regression analyses while controlling for PTSD and alcohol abuse and dependence severity.

Results

Our hypotheses were partially supported. We found that negative trauma-related cognitions were uniquely associated with greater psychosocial functional impairment, independent of PTSD and alcohol abuse and dependence severity. Specifically, negative trauma-related cognitions about the self were associated with greater psychosocial functional impairment across all domains, cognitions about the world were associated with worse social functioning and psychological well-being, and self-blame was associated with impaired psychological well-being.

Conclusions

Given that improvements in negative trauma-related cognitions are a mechanism of trauma-focused treatment, future studies should examine whether changes in negative trauma-related cognitions through trauma-focused treatment are associated with improved psychosocial functioning.
